To all whom it may concern:

Be it known that 1, MICHAEL J. Solomon", a -citizen of the llnitedStates, residing at Dover, in the county of Kent and State of Delaware,have invented new and useful improvements in Impulse-Turbines, of whichthe following is a specification.

This invention relates to impulse turbines, and the primary object ofthe same is to provide a turbine of this class having a superioroperation and provided with means whereby the motive fluid is thrown outfrom the center by the rotation of an impulse drum against motionaugmenting devices connected up to the shaft of the drum and operated bythe motive fluid thrown out towards the periphery of the drum, theturbine operating as a source of power for driving mechanisms of variousforms.

it further object of the invention is to provide an impulse turbinehaving a compara tively simple construction and etlective operation andof a strong and durable nature.

in the drawings: Figure 1 is a side elevation, partially in section, ofa turbine embodying the features of the invention. Fig. 2 is a top planview of the impulse drum.

Similar characters of reference are cur ployed to indicate correspondingparts in the views.

The numeral 1 designates the impulse drumprovided with a central chamberhaving curvilinearwalls 3 and 4 which are braced and held in adjustedposition by radially arranged bars 5 extending outwardly to theperiphery of the drum. The chamber has a closed top 2" and a bottom 2"also closed except where a depending teed-sue tion pipe 6 communicatestherewith at the center, the said pipe being open and connecting at itslower extremity with a suitable motive fluid supply. The impulse drum 1'is rotatably supported within a frame 7 through the medium of avertically extending shaft 8 mounted at its lower end in a bearing 9carried by the closed bottom of the said frame 7, the shaft at its upperextremity within the frame 7 being provided with a beveled gear 11 fixedto the top of the said frame. The upper end of the shaft projectingthrough the top oi the frame 7 has a hand pulley 12 fixed thereon fromwhich motion may be. transmitted to mechanism to be driven. The drum 1hetwcen the peripheral wall thereof and the walls 3 and 4 is hollow at13 and 1 1, and open at the bottom as shown by Fig.

1; and arranged atoppostte ends of the hollow spaces 13 and 1 1 arevertically extending shafts 1:3 and 16 supported at their lower endsupon brackets 17 radially projecting outwardly from the bottom 2" of thechamber 2, the shafts 15 and 16 at their upper ends extending throughhorizontal arms of brackets 18 and carrying beveled pinions 19, thelatter being held in continual mesh with gears 20 fixed on the oppositeends of a horizontal or counter-shaft 21 having bearings at oppositeextremities in vertical members of the said brackets 18. The shaft 21also car ries a beveled pinion 22 held in continual mesh with the pinion11 fixed to the top 10 of the frame 7.

The bottom portions of the hollow spaces 13 and 1e are fully open sothat the motive fluid contents thereof may fall into a fixed collectingreceptacle 29' held on. the bottom of the frame 7 and having a train ofoutlet pipes 29. Each of the shafts 15 and 16 car ries'an impulse wheel23 horizontally disposed and having outwardly projecting blades, each ofthe said impulse wheels being disposed in operative relation withrespect to a nozzle 24 located at the ends of the chambers 13 and 14:adjacent to-the said impulse wheels. These nozzles are in opposedpositions in their respective spaces 13 and 14,

the said spaces constituting outlet chambers for the relief of thechamber 2, the communication between the latter chamber and the, spacesor outlet chambers 13 and 11 being etl'ected through the nozzles. :21.Two impact wheels, one on each shaft 15 and 16, are shown to demonstratea practical-apparatus, but it will be understood that the number ofthese wheels may be increased and the number of nozzles correspondinglymultiplied.

Secured on the bottom of the frame 7 is a slotting-box 25 for the lowerend of the motive fluid supply pipe 6, the stuliing-box surroundin thebearing 9 at the lower end of the shat. Connected to the bottom of theframe 7, as at 26, is a cut-oil 27 consisting of suitable valve, andcommunicating therewith is a motive fiuid supply pipe 28. It will beunderstood that when the cut-off 2T opened the motive fluid may passfrom the pipe 28 upwardly through the stuffingbox the latter beingtul'ailar or hollow, into the reed pipe 6. When the cut-oil is closed,the supply o'l' motive fluid to the turbine will be interrupted, as willbe appreciated.

operation of the turbine-as shown by through the nozzles 24 Figs. 1 and2 is as follows: The motive fluid passing into the chamber 2 will bethrown out andact upon the curvilinear Walls 3 and 4 and be directed bythe latter in reverse directions towards the nozzles 2e,

and the discharge of the fluid through the nozzles will efiiectarotation of the impulse drum 1 after the manner of the operation of aHerosfountain, and the fluid passing through the nozzles 24 will beclirecteii against the impulse wheels 23, thus breaking up the fluidcurrent 01'- foroeox the fluid and preventing obstructive action ofsaid; fluid that might ensue if it was permittetl' to pass Itwill beobserved that the incoming motive fluid under pressure has but twooutlets from the chamber 2, namely through the nozzles 24, and. as thesenozzles are mate rially reduced ascompared to the capacity of thechamherii, the force of the fluid escapingthrough the nozzles will setup sutiicient momentum with relation to the impulse drum 1 to rotate theshaft with consitierahle power. A uniformity of rotation of the impulseWheels 23 is maintaineilh y ii1- tergearing the said Wheels with theshaft 21 and the pinion 11 as hereinbefesfe e2:- glained, and the motivefluid after having een deprived of its force falls into the c0ieoeeselasting receptacle 29* and escapes through the pipe 29, r

It will be evident from theforegoing construction that the shaft 8 canbe operated with power'advantageswhich "will he de-- pendent upon theinitial force orpressure of the motive fluid entering theturhine.

Having thus described the invention, What is claimed asnew, is: v v

An impulse turbine comprising an inclosing frame, a shaftextendingtherethrough and rotatable therein, an impulse Chaim fixed orthe shaft and. provided with a. central receptaclelbelow the drum and.its outlet chambers, gearing for renderihg the operation otthe impulseWheels unitorimotner gear devices for transmit ing the motion of saidgearing to the firemanctineans tor controlling" the supply of a motivetluicl to the drum.

In testimony whei'eof I have hereunto set 7 my hand in presence of twosubscribing witnesses. V c MICHAEL Jfi-GANLG-lil viiitness'esy e EDWARJL Soaivhoiq Josseti H. Dmzma if,
